Docker and Kubernetes: The Complete Guide

This course builds from Docker fundamentals (what a container actually is, namespacing, control groups) through custom image creation, Docker Compose for multi-container apps, a full CI/CD pipeline with GitHub, Travis CI, and AWS Elastic Beanstalk, and finally production-grade Kubernetes clusters — building a complete multi-container Fibonacci-calculator application along the way to tie every concept to a real deployed app.

The honest take: at 62,495 reviews and Highest Rated status, this is one of the most established Docker/Kubernetes courses on the platform — a few recent reviews note that Travis CI's free tier has since been discontinued, requiring a workaround for that specific section, but the Docker and Kubernetes fundamentals remain current and thorough.
